Answer:
2.5 weeks
Explanation:
The average travel time on a voyage that allows C&A Cruise to meet its desired goal of 2,000 passengers per week is determined by their total capacity over the 10 ships (10 x 500), divided by the weekly flow of 2,000 passengers.
[tex]t = \frac{10*500}{2,000}\\t=2.5\ weeks[/tex]
The longest average travel time possible is 2.5 weeks.
